  1. a Missing fall data from 11 individuals from intervention clinics and 2 from control clinics, missing UI data from 4 individuals from intervention clinics and 3 from control clinics
  2. b Sensitivity of a clinical test refers to the ability of the test to correctly identify those patients with the disease. Calculated by true positives/(true positive + false negative)
  3. c Specificity of a clinical test refers to the ability of the test to correctly identify those patients without the disease. Calculated by true negatives/(true negative + false positives)
